Emergency fan-out-panel (EFOP)

To be able to make emergency calls even in the event of a mains power failure, you
have the possibility of running up to 8 analogue FXO exchange lines via the EFOP
(emergency fan-out-panel). In the event of power failure, the EFOP automatically and
directly switches over exchange lines to up to 8 analogue phones.
The EFOP fan-out-panel also monitors the voltage of the FXS lines to the communica-
tion server. If for example ports are switched off due to overloading, the corresponding
exchange lines switch over automatically and directly to the analogue phones.

In the following, these analogue phones are referred to as emergency phones. In nor-
mal operation emergency phones act like ordinary internal phones. Only phones capa-
ble of operating without their own power supply are suitable as emergency phones.
Both DTMF and pulse dialling phones are supported. It is recommended to identify
emergency phones as such.
The fan-out panel EFOP takes up the space of one height unit in a rack and can be fit-
ted directly above or below the communication server.
Detailed Description
The block diagram below illustrates how the EFOP fan-out-panel operates. The lines
are switched over by relays. When relays are in a de-energised idle state, the emer-
gency phones are connected directly with the analogue exchange lines (PSTN). For
each port the relay switching status is indicated by an LED.
